Casual video game publisher PopCap Games announced today that it’s working on a sequel to its popular tower defense title Plants vs. Zombies. The original game, which features comic zombie characters attacking a house defended by plants, was a smash hit when it debuted in May 2009. It sold more than 300,000 copies in its first nine days, setting a record for Apple App Store launches.

The sequel will include “a bevy of new features, settings, and situations.” PopCap released no other details about the game at this time, although it did offer up this amusing quote from an unidentified “spokesperson.”

“Spring is crullest curlie ungood time, and plantz grow dull roots. So, we are meating you for brainz at yore house. No worry to skedule schedlue plan… we’re freee anytime. We’ll find you.”

Plants vs. Zombies 2 is expected to launch by late spring.
